5
6FU540-C000 RISC-V SoC
7---------------------
8The FU540-C000 is the worlds first 4+1 64-bit RISC-V SoC from SiFive.
9
10The HiFive Unleashed development platform is based on FU540-C000 and capable
11of running Linux.
12
13Mainline support
14----------------
15The support for following drivers are already enabled:
16
171. SiFive UART Driver.
182. SiFive PRCI Driver for clock.
193. Cadence MACB ethernet driver for networking support.
20
21TODO:
22
231. U-Boot expects the serial console device entry to be present under /chosen
24 DT node. Without a serial console U-Boot will panic. Example:
25
26.. code-block:: none
27
28 chosen {
29 stdout-path = "/soc/serial@10010000:115200";
30 };
31
32Building
33--------
34
351. Add the RISC-V toolchain to your PATH.
362. Setup ARCH & cross compilation enviornment variable:
37
38.. code-block:: none
39
40 export ARCH=riscv
41 export CROSS_COMPILE=<riscv64 toolchain prefix>
42
433. make sifive_fu540_defconfig
444. make
45
46Flashing
47--------
48
49The current U-Boot port is supported in S-mode only and loaded from DRAM.
50
51A prior stage (M-mode) firmware/bootloader (e.g OpenSBI or BBL) is required to
52load the u-boot.bin into memory and provide runtime services. The u-boot.bin
53can be given as a payload to the prior stage (M-mode) firmware/bootloader.
54
55The description of steps required to build the firmware is beyond the scope of
56this document. Please refer OpenSBI or BBL documenation.
57(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
58(Note: BBL git repo is at https://github.com/riscv/riscv-pk.git)
59
60Once the prior stage firmware/bootloader binary is generated, it should be
61copied to the first partition of the sdcard.
62
63.. code-block:: none
64
65 sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024
66
67Booting
68-------
69Once you plugin the sdcard and power up, you should see the U-Boot prompt.
